How do you guys do your intro pads?

I am in the process of doing a track and I have done the first 16 bars of the main drop. I need to start working on the drop and obviously the intro but am stuck on how to create those fat intro pads you hear in a lot of professional tunes these days.

For example, listen to the start of sub zer & majistrate - under pressure. - Are these sounds one long note that has been created on massive? could I recreate one by literally making the note x bars long and trying to engineer the sound that way? I find it hard to understand these things.

I use massive on FL 12. If anyone can direct me in the right direction or give me some of their own advice I would make good use of it!

samplers mate, they are your friend, use them for pads and ting.
I'd recommend Kontakt for a standard sampler, its quite epic in scope but the raw sounds that come with are incredible. For a granular sampler try out alchemy, theyve gone bust now but you can still get hold of the computer music version for some fun. The Mangle is also a good one I've been using, you can literally turn a snare into a sweeping pad. It's also a lot cheaper than kontakt and easier to understand.
then youve got paul stretch, google it. Its a freeware program that can stretch audio like nothing else. Try putting in 1 seconds worth of shitty noise stuff and stretch it as far as you dare! Insta-pad

Quite the contrary: using the randomize function can give you a inspirational boost to work on a new track. Since my focus is ambient stuff, most of them come out with just randomized sounds generated this way.

In other words: I suck hard at synthesizing things. too many buttons, I tend to get lost. So the best approach for me is to let the machine do the stuff, and I only fine tune the sounds to what I need.
